DAVEX MK-30 is a new type of surface sizing agent that synthesized by the copolymerization of styrene and ester. It can efficiently combines with starch that endows starch coating layers with good cross lik intensity and hydrophobic properties. It has the advantage of less dosage, low cost and easy use. Also it has good film- forming property which can improve the water- resistance, ring- Cush strength of board paper and corrugated paper Benefits: Effective waterproofing in a wide temperature range/ No affect the color of the paper/ Easy to disperse in water/ Less foam when operating/ Non- toxic to be contained in food packaging material
